small lateral lobes (pr"), lying along the sides of the neck of the 

 bladder. 



275. Cowper's glands (c.gl), a pair of brown, ovoid masses, imme- 

 diately behind the posterior lobe of the prostate, and enclosed in a 

 layer of muscle. 



276. The rectal glands (r.gl), two brown elongated 

 glands, about an inch long and a quarter of an inch wide, 

 situated one on either side of the rectum. 



277. The perineal glands * (p.gl), similar in appear- 

 ance to the rectal glands, but not more than half an inch 

 long : they lie, one on either side of the extremity of the 

 penis, and are in relation externally one with each of the 

 hairless perineal spaces, on the surface of which its duct 

 opens on a small papilla (/.#"/'). 



278. By slitting open the uterus masculinus along its 

 dorsal wall, the vasa deferentia are seen to open into its 

 ventral wall, near its junction with the bladder. 



279. The corpus spongiosum (c.s), a quantity of 

 extremely vascular tissue surrounding the urethra, from 

 about the posterior boundary of Cowper's glands to the 

 glans penis, with which it becomes continuous : to see it 

 satisfactorily, the rectum and rectal glands should be 

 entirely removed. 



XXX. Turn the organs with the ventral side upper- 

 most, and make a median incision along the 

 whole length of the penis, beginning at the 

 glans and cutting through the fibrous septum 

 between the corpora cavernosa : continue the 

 incision forward so as to open the bladder along 

 its ventral wall. Note : 



280. The small apertures of the ureters in the dorsal 

 wall of the bladder at about the junction of its middle and 

 posterior thirds.
